chronological gaps in our knowledge based on our orbit. Our orbit suggests that the predawn celestial show in the east ended a couple of days after the birth, namely on October 22, and that this would have become evident to observers by October 23. We should therefore reckon on the Magi departing their homeland at some point between October 23 and 25. A quick departure is strongly supported by the observation that at that time the comet, having shifted to the western sky, becomes capable of functioning as a westward prompt or guide for the Magi.
In light of this and our earlier conclusions regarding the duration of the Magiâs journey (approximately 28â37 days) and their stay (2â5 full days, leaving on the 3rdâ6th day), we are in a position to set out two scenarios regarding the chronology of the Magiâs visit to Bethlehem: either (A) it occurred in the week running up to the holy familyâs trip to the temple (on November 29)âthat is, the week of November 21â28; 15 or (B) it took place in the week immediately following itâthat is, sometime in the week following Mary and Josephâs return from Jerusalem on the afternoon of November 29âthat is, November 29âDecember 6. 16 In Scenario A, assuming a departure date between October 23 and 25, the Magiâs camel caravan advanced approximately 17â18 miles per day toward Jerusalem and arrived in Bethlehem between November23 and 25, and they departed on or before the 28th. In Scenario B, having left BabÂylon on October 24 or 25, the camel caravan got 15 miles closer to Jerusalem each day, and the Magi arrived in Bethlehem late on November 29 or on the 30th, in the immediate aftermath of Mary and Josephâs return from Jerusalem, and departed for BabÂylon between December 2 and 6.
In our analysis we shall consider two representative dates for the arrival of the Magi in Bethlehem: November 23 (= an average journey speed of about 18 miles per day if they left BabÂylon on October 24); and November 30 (= an average journey speed of about 15 miles per day if they left BabÂylon on October 25), 6Â BC. 17
According to our reckoning, Herodâs decree to massacre the infants was issued on (or around) either November 30âDecember 2 or December 3â7, 6Â BC. The Starâs initial appearance (1â2 Jewish luni-solar years before Herod issued his order) was therefore either between November 21â23, 8Â BC, and December 10â12, 7Â BC; or between November 24â28, 8Â BC, and December 13â17, 7Â BC. 18
We propose, then, the following approximate chronology:
Between November 21â28, 8Â BC, and December 10â17, 7Â BC: The Star first appears.
September 15, 6 BC: The Moon is observed under Virgoâs feet.
September 29/30, 6 BC: The cometary coma rises heliacally in Virgoâs womb.
October 15, 6Â BC: Virgo appears to begin active labor.
October 19, 6 BC: A meteor storm radiates from Hydraâs tail.
October 20, 6 BC: The cometary baby, having descended, has completely emerged from Virgoâs womb and so is regarded as having been born.
Between October 23 and 25, 6Â BC: The Magi leave BabÂylon on their mission to worship the Messiah in Judea.
SCENARIO A
Between November 23 and 25, 6 BC: The Magi arrive in Jerusalem and, that same evening, are ushered by the Star to Bethlehem. Later that night the comet stands as it sets, pinpointing the house where Mary and Jesus are.
Between November 26 and 28, 6Â BC: The Magi depart Bethlehem to return home to BabÂylon.
November 29, 6Â BC: Mary, Joseph, and baby Jesus visit the Jerusalem temple on the 40th day to fulfill their religious obligations, and return to Bethlehem.
November 30âDecember 2, 6Â BC: Herod the Great orders the Massacre of the Innocents in the vicinity of Bethlehem.
SCENARIO B
November 29, 6Â BC: Mary, Joseph, and baby Jesus visit the
